GAS-REGULATOR FOR CALCIUM LIGHTS.

SPECIFICATION forming part of Letters Patent No. 498,897, dated June 6, 1893. Application filed January 6, 1893- Serial No. 457,495. (No model.)

To all whom it may concern.-

Be it known that I, JOHN VON EY, a citizen of the United States, residing at Chicago, in the countyof Cook, State of Illinois, have invented certain new and useful Improvements in Gas-Regulators for Calcium Lights, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in gas regulators for calcium lights and the like, and it has for its objects'among others to provide a simple and cheap construction and combination of parts whereby the pressure of gasin the two cham bers may be regulated and the device rendered automatic in its operation.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure 1 is a view partly in elevation and partly in section of my improvements. Fig. 2 is a cross section through one of the valves, on the line 2-2 of Fig. 1, looking downward.

Like letters of reference indicate like parts in both of the views where they occur.

Referring now to the details of the drawings by letter, A designates one of the cylinders and A the other, these cylinders being provided with suitable inlets a and a. respectively which are fitted for suitable connection as A with the source of supply of oxygen gas and hydrogen gas, such connection being detachable by any suitable means to form a tight joint and the cylinders being of any desired material and of the required capacity. These two cylinders are connected together near their upper and lower ends by the bands B which are fitted into grooves or recesses 12 in the cylinders as seen in Fig. 1 and between the two cylinders formed with enlargements b to form guides for the central rod and the spool which slides thereon as will hereinafter appear.

The cylinders are provided with caps B which are shown as screwed thereon, and the lower portions are also shown as detachably connected therewith below the diaphragm A in which latter are openings through which work the valves. These lower portions B form small chambers into which the gases are first admitted as will be readily understood from Fig. 1.

In each cylinder is a piston C which may be of any desired form of construction, being shown as providedwith the peripheral packing rings 0 held in grooves in the outer face of the piston heads but these are not absolutelynecessary. These piston heads are carried by the piston rods C the said rods having one end fitted 'to work freely through the openings in the diaphragms A and said lower portions which may or may not be enlarged as shown in Fig. 1, are formed with elongated substantially V-shapedopenings or passages c for a purpose which will soon appear. To the opposite sides of the piston heads are detachably screwed or seen red the rods D which pass loosely through the heads of the cylinders as seen in Fig. 1 and are provided with collars or flanges d to limit their inward movement, and to the outer ends of each of these rods 1) are pivotally connected the short rods E the outer ends of which are pivotally connected by the transverse rod or bar F, which at its center is pivotally connected as at e with the rod G which is passed through openings in the enlargements b of the bands B as shown. This rod G is provided with a collar, flange or stop g to limit its inward movement and its opposite end is screw threaded and receives a nut H which has a milled face to facilitate its manipulation and around this end of the rod is asleeve I which is adapted to be moved nearer to or farther from the pivot end of the rod by the manipir lation of the said nut as will be readily understood from Fig. 1. Between this sleeve and the upper band B is arranged a spring J which surrounds the rod G and the tension of which may be regulated by the adjustment of the nut upon the end of the rod.

K are the outlets from the cylinders which are designed to be so connected as to deliver the gas in the usual way.

The operation will be readily understood from the foregoing description when taken in connection with the annexed drawings. The oxygen gas is admitted to one cylinder and the hydrogen gas to the other cylinder in the usual manner. As the cylinders become filled their pistons will advance and as they advance the valves on the ends of the piston rods advance with them and as they advance the opening for the flow of gas is gradually decreased in size owing to the peculiar shape of the passage, and owing to the manner of supporting the piston rods the pressure on or in both of the cylinders must be the same and is automatically and simultaneously adjusted by the spring-held rod centrally arranged between the cylinders. The pressure may be regulated by adjustment of the nut H which adjusts the tension of the spring. As the gas is used the pressure is relaxed and the valve open to admit more gas.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

lVhat I claim as new is 1. The combination with the cylinders, of the pistons therein with external connections, and carrying valves, and the spring-actuated rod pivotally connected with the connection between the piston rods, and means for regulating the tension of the spring which actuates the red, as set forth.

2. The combination with the cylinders, of

' the pistons in the cylinders, valves on the piston rods, external pivotal connections between the piston rods, and a spring-actuated rod pivotally connected with the connection between said rods, and provided with means for adjusting the tension of the spring, as set forth.

3. The combination with the cylinders and their pistons, and piston rods provided with substantially V-shaped openings therethrough to serve as valves, of the pivotal connections between the rods, the rod connected with the connection between the piston rods, a spring around said rod, the nut on the rod and the sleeve between the nut and spring for adj usting the tension of the latter, substantially as described.

4. The combination with the cylinders and their pistons and valves and piston rods, of the pivotal connections between the rods, the spring-actuated rod connected with the connection between the piston rods, the nut on the rod the spring and the sleeve on the rod JOHN VON EY.
